Practice questions on Java Classes and Objects – Find fare on the basis of distance

Define a class Tour with the following description:

• Members are : TCode of type String, NoofAdults of type integer, NoofKids of type integer, Kilometers of type integer, TotalFare of type float.
• Member functions :
• A constructor to assign initial values as follows:
• TCode with word “NULL”, Other members initialize with 0.
• A function AssignFare() which calculates and assigns the value of the data member TotalFare as follows:
• For each Adult

• For each kid the above Fare will be 50% of the fare mentioned in the above table.
• A function EnterTour() to input the value of the data members TCode, NoofAdults, NoofKids and Kilometers; and invoke the AssignFare() function.
• A function ShowTour() which displays the content of all the data members for a Tour.

Solution

import java.util.*;

class Tour 
{
    String TCode;
    int NoofAdults;
    int NoofKids;
    int Kilometers;
    float TotalFare;
    
    //define a constructor
    Tour ()
    {
        TCode=null;
        NoofAdults=0;
        NoofKids=0;
        Kilometers=0;
        TotalFare=0.0f;
    }

    public void AssignFare(){
        if(Kilometers>=1000)
        {
            TotalFare=NoofAdults*500+NoofKids*250;
        }
        if(Kilometers>=500 && Kilometers<1000)
        {
            TotalFare=NoofAdults*300+NoofKids*150;
        }
        if(Kilometers<500)
        {
            TotalFare=NoofAdults*200+NoofKids*100;
        }
    }

    public void EnterTour(){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter Travel Code : ");
        TCode=sc.next();
        System.out.println("Enter Number of Adults : ");
        NoofAdults=sc.nextInt();
        System.out.println("Enter Number of Kids : ");
        NoofKids=sc.nextInt();
        System.out.println("Enter Distance in Kilometers : ");
        Kilometers=sc.nextInt();
        AssignFare();
    }
    

    public void ShowTour(){
        System.out.println("Travel Code   : "+TCode);
        System.out.println("No of Adults  : "+NoofAdults);
        System.out.println("No of Kids    : "+NoofKids);
        System.out.println("Dist in Kms   : "+Kilometers);
        System.out.println("Total Fare    : "+TotalFare);
    }
}

class Travel
{
   public static void main(String args[])
   {
     Tour ob=new Tour();  
     ob.EnterTour();
     ob.ShowTour();
   }
}

Save the above Program with “Travel.Java” then compile it with the following commands :

javac Travel.java    //to compile the code

java Travel         // to run the code

Output is

Enter Travel Code :
101
Enter Number of Adults :
4
Enter Number of Kids :
3
Enter Distance in Kilometers :
2400

Travel Code   : 101
No of Adults  : 4
No of Kids    : 3
Dist in Kms   : 2400
Total Fare    : 2750.0
